You wear the same pajamas year-round
What you wear matters, even while you sleep. Your body temperature plays a part in your sleep cycle—a slight drop in temperature is what induces sleep, says Raj Dasgupta, MD, a fellow of the American Academy of Sleep Medicine and assistant professor of clinical medicine at the Keck School of Medicine at the University of Southern California. That means being too hot or too cold can prevent you from getting a good night’s rest. Silk is ideal, according to Sleep.org, because it keeps you warm when you’re cold and cool when you’re hot. If silk is too pricey, try breathable cotton in the warmer months and cozy flannel during the cold. These innocent habits are completely ruining your sleep quality, too.
